Sorry but I'm really not getting your point here. You started off saying that GPUs are "bottlenecking CPUs". That's completely false. A cheap CPU is enough to run most games but we need expensive GPU hardware. That's cause games don't need much CPU power but a lot of GPU speed. That's not the fault of GPU manufacturers or GPU hardware, it's just a fact based on how the software is written.

A bottleneck occurs when a component is unable to do more work because it's held up by another component. That's not the case here. CPUs don't do more work cause the software isn't giving them more work to do.
